PUZZLE.

SPECIFICATION fortning part of Letters Patent No. 527,925, dated October23, 1894.

Application filed January 24,1894- Serial No. 497,878. (No model.) 7

To aZZ whom it mayconcern:

Be it known that I, ALBERT W. BARTHOLO MEW, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and usefullmprovements inPuzzles, of which the following, taken in connection with theaccompanying drawings, is a specification.

The object of my invention is to producea puzzle box or receptacle thatcan be locked or unlocked byalocking pin held or released by themovement of a rotating disk, and the invention consists of a centralbody forming the box or receptacle having two disks at each end, thedisks at one end forming the cover and being eccentrically pivoted tothe body so that they can be pushed on one side when released, the innerone of said disks being formed with a hole toreceive a locking pin andone of the disks at the other endbeing formed with a recess into whichthe locking pin falls to release the upper disks as hereinafter fullydescribed and pointed out in the claim.

Referring to the accompanying drawings: Figure 1 represents a side viewof a puzzle box embodying my invention, arranged in the form of adarning ball. Fig. 2- is avertical section of the same showing it in thelock ed position. Fig. 3 is a similar view showing the locking pin inthe position to release the cover. Fig. 4- is a plan or top View showingthe cover open. Fig. 5- is a side view showing the box or receptacle inthe form of a barrel.

A, represents the body of the box or receptacle which is preferably of acylindrical form and which is formed with a chamber a, to receive anydesired article or articles. I To one end of the body A, is secured adisk B, by a pin 0. To the disk B, by a centralpin D, is attached a diskE. To the lower end of the box or receptacle by a central pin F, aresecured two revolving disks G. H.

In one side of the body A, opposite the pin (3, is formed a verticalhole I, and in the disk B, is a corresponding hole or recess J. In thehole I, is placed a locking pin K, adapted to slide vertically, the headof which fits into an enlarged recess in the body A, at the lower end ofthe hole I.

In the disk G, is formed a hole L that registers with the hole I, whenin the position for unlocking, so that the locking pin K, will falltherein thus releasing the upper disk B, so that it and with it the diskE, can be turned on one side so as to expose the opening a, as will bebest seen in Fig. 4.

The operation is as follows: Supposing the box to be in the closedposition, that is to say, with the locking pin K, projecting up into thedisk B, and it is desired to open the box, then the disk G, is turneduntil the hole L, in the disk G registers with the hole I, in the bodyA, when the locking pinK, will fall therein thus releasing the disk 'B,so that it and with it the disk E, may be pushed on one side so as touncover the hole or opening a, in the body A. To lock the box the disksB, E, are pushed into their normal position which allows the locking pinK, to fall into the opening J, therein. The disk G, is then partiallyrotated and the box is locked.

It will be seen that by having both ends constructed alike, the persontrying to open the same does not know one end from the other, and as thedisks E, H, G, are always free to be rotated, he does not know which hasto be 0perated to release the cover.

I prefer to make the puzzle box in the form shown so that it can be usedfor a darning ball, but it could be made in the form of a barrel asshown inFig. 5, or of any other desired shape.

What I claim is- A puzzle box consisting of a hollow body, two disks ateach end of same, the disks at the upper end being pivoted centrally toeach other and eccentrically to the body so that they can be movedlaterally to expose the opening in the body, and the disks at the lowerend being pivoted centrally to the body, a locking pin passing throughthe body and openings in the inner disks at each end adapted to registerwith the opening in. the

body containing the locking pin substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 2d day of [on January, A.D. 1894. v

ALBERT W. BARTHOLOMEW.
